如何在DataStore中存储* time.Time类型的struct字段的当前时间？ [重复]

According to my requirements, I created one struct as -

type MyRule struct {
   CreatedAt    time.Time  `json:"createdAt" datastore:"createdAt,noindex"`
   UpdatedAt    *time.Time  `json:"updatedAt" datastore:"updatedAt,noindex"`
}

for createdAt field, I am able to store current time as-

MyRule.CreatedAt = time.Now()

However, the same thing does not work to store current time in updatedAt field of MyRule struct as it's type is *time.Time and not time.Time. Here, I can't change field type of updatedAt because *time.Time allows me to accept nil as updatedAt value when I create any rule.

If I try to do this as-

 MyRule.UpdatedAt = time.Now()

It gives me below error-

 cannot use time.Now()(type time.Time) as type *time.Time in assignment

How can I store current time value in updatedAt field of type *time.Time and not time.Time

</div>

Note: one cannot get the address of a return value, so something like this will NOT work:

MyRule.UpdatedAt = &time.Now() // compile fail

To get the address of a value, it must be in an addressable item. So assign the value to a variable, like so:

t := time.Now()
MyRule.UpdatedAt = &t
